22. Odour (1) SG8 and SNIFFER Report SG8 and SNIFFER Report Environment Agency H4 Odour Management Guidance - March 2011 Environment Agency H4 Odour Management Guidance - March 2011 Permit conditions (a) compliance with odour management plan (b) no pollution beyond the site boundary; use of BAT Permit conditions (a) compliance with odour management plan (b) no pollution beyond the site boundary; use of BAT Odour management plan should identify potential sources of odour and be designed to: Odour management plan should identify potential sources of odour and be designed to: - Employ appropriate methods, including monitoring and contingencies, to control & minimise odour pollution - Prevent unacceptable odour at all times - Reduce the risk of odour releasing incidents or accidents by anticipating them and planning accordingly

23. Odour (2) Unreasonable odour amounting to serious pollution is being or is likely to be caused (regardless of whether appropriate measures are being used). Must take further action or you may have to reduce or cease operations – Agency would not issue a permit if considered to be operating at this level. Odour pollution is or is likely to be caused beyond boundary. Operator’s duty is to use appropriate measures to minimise odour. If appropriate measures are being used, residual odour will have to be tolerated by the community. No odour beyond the boundary or likely to be = no pollution = no action necessary Three levels of odour Benchmark Level

24. Odour (3) I n any particular case NIEA has to decide: I n any particular case NIEA has to decide: (1) Is there serious pollution? Conclusion best based on a number of assessment techniques (a) Subjective assessment FIDOR – Frequency; Intensity; Duration; Offensiveness; Receptor sensitivity (factors which determine degree of odour pollution) – (NIEA Odour Impact Assessment Guidance) FIDOR – Frequency; Intensity; Duration; Offensiveness; Receptor sensitivity (factors which determine degree of odour pollution) – (NIEA Odour Impact Assessment Guidance) (b) Air dispersion modelling/Measurement 1 Odour unit, OU/m3 = point of detection (when ½ population should detect odour) Odour benchmark levels (modelled 98 th percentile hourly average): Odour benchmark levels (modelled 98 th percentile hourly average): 1.5 most offensive eg. rendering – (but <1 if neighbour sensitised) 3.0 moderately offensive eg. int agric, feed mills 6.0 less offensive odours eg. bakery Results above benchmark level indicates the likelihood of Results above benchmark level indicates the likelihood of unacceptable odour pollution and enforcement action

25. Odour (4) (2) Is the operator taking appropriate measures? BREFS; H4 odour guidance; industry guidance and best practice (SNIFFER report) BREFS; H4 odour guidance; industry guidance and best practice (SNIFFER report) When determining what appropriate measures will be for a site NIEA will factor in needs, costs & benefits. In practice this means the higher level of pollution the more measures you will be expected to take and the greater the justifiable financial investment will be. When determining what appropriate measures will be for a site NIEA will factor in needs, costs & benefits.

28. Effluent Treatment Plants The sector produces large effluent volumes with high Ammonia, BOD and SS in effluent and some plants discharge directly to a water course, however most discharge to sewer. The primary goals of the ETP are: Removal of organic matter (BOD), removal of Suspended Solids, Ammoniacal Nitrogen and Total Phosphorus.

29. Effluent Treatment Plants Objective: Protecting receiving water quality Solids “suffocate” benthic organisms and may increase turbidity and decrease light penetration Solids “suffocate” benthic organisms and may increase turbidity and decrease light penetration BOD/COD – oxygen depletion in water and harms the environment i.e. Fish kills, Septicity, Odours BOD/COD – oxygen depletion in water and harms the environment i.e. Fish kills, Septicity, Odours Ammonia Nitrogen – Toxicity, pH changes, Eutrophication Ammonia Nitrogen – Toxicity, pH changes, Eutrophication Phosphate - Eutrophication, Drink Water Standards Phosphate - Eutrophication, Drink Water Standards

30. Effluent Treatment Plants Critical Monitoring required on site: Influent: Daily Composite sample tested for Ammonia, COD/BOD, SS, Phosphorus, and Fat. Continuous Flow & pH Post solids removal, balancing tank & DAF plant: COD/BOD, SS, Ammonia and continuous pH.

37. Rendering Sector Compliance Issues and Learning

38. Thermal Oxidiser Trips Thermal Oxidiser trips recorded on all NI plants, but frequency varies. Example reasons: – –Electrical faults; – –Water pressure / level faults; – –Burner faults Unabated / less abated releases following trips can cause significant off site odour.

39. T.O. Trips: Learning Points Analyse causes of trips and implement corrective action. Ensure preventative maintenance programmes reflect the manufacturer’s recommendations and your operating experience.

40. Process changes : Impact on Effluent Treatment Plants Process change led to transfer of high BOD, high ammonia effluent at increased volume which ETP was incapable of treating. Extended non compliance, high costs for effluent transfer, enforcement action.

41. ETP overloading: Learning Points ETP capacity needs to be designed to match actual or changed duty. Management of Change – evaluate consequences of process changes on ETP as part of decision making / approval process. Failure to assess these aspects can lead to significant environmental and business risk. Contingency plans for ETP failure.

42. Raw Material Management Storage and handling of raw material: – –Vehicle management / external operations; – –Spillages during unloading; – –Internal housekeeping; – –Management of material in the event of a breakdown.

43. Raw material: Learning Points Ensure employees are aware of permit requirements and procedures for handling and storage of material. Procedures for assessing quality of material and appropriate response: rejection or other sanctions Prompt cleaning of internal and external spillages. Diversion plans are in place in the event of a breakdown or other unplanned event.

44. Common issues for food and drink sector ETPs – design, monitoring, control, training. ETPs – design, monitoring, control, training.

59. Integrated Permitting Tiers of Control General Binding Rules – small risk Registration – cumulative impacts Standard Permits – sector based Bespoke Permits – complex and high risk

60. Unified Inspection and Investigatory Powers Currently: – over 200 pieces of environmental legislation – about 50 with powers of inspection and investigation. Aim: To consolidate and define investigatory powers for officers carrying out inspections.

61. Risk Based Inspections

62. Enforcement Currently: Penalties applied through criminal justice system with monetary fines and, in extreme cases, custodial sentences. Aim: To see a more consistent, flexible and proportionate environmental penalties and sanctions regime.

63. Penalties and Sanctions Compliance notice to secure that an offence does not continue or recur. Restoration notice to restore harm caused by an offence. Stop notice prohibiting a person from carrying out an activity which is, or is likely, to present a significant risk of serious harm to human health or the environment. Enforcement Undertaking sets out how the alleged offence does not continue or recur; what actions will be taken to ensure that restoration will be secured; or what equivalent benefit or improvement to the environment is being offered.
